“…Some authors [41] claim that the observed high antioxidant potential of raspberries can be attributed to an elevated concentration of anthocyanins. As it was mentioned in the introduction, cyanidin 3-glucoside is the most quantitatively predominant anthocyanin in blackberries [7][8][9][10], while in red raspberries other cyanidins: cyanidin 3-sophoroside, cyanidin 3-glucosylrutinoside, cyanidin 3-glucoside and cyanidin 3-rutinoside occur in different proportions, depending on the cultivar [9,[11][12][13]. In the method of Fukumoto and Mazza used in this study, the values were expressed as equivalents of cyanidin 3-glucoside per 100 g fw.…”

“…Some of them can modulate gene expression and cellular pathways as well as affect enzyme and hormone activities [5,6]. Recent analyses revealed the presence of eight anthocyanins in cultivated blackberries [7]; however, the majority of the content belongs to cyanidin 3-glucoside [7][8][9][10]. Tornless cultivars produce larger amounts of anthocyanins, ellagitannins and ellagic acid derivatives while the torny ones are characterised by higher levels of hydroxycynnamic acids and flavonols [7].…”

“…Tornless cultivars produce larger amounts of anthocyanins, ellagitannins and ellagic acid derivatives while the torny ones are characterised by higher levels of hydroxycynnamic acids and flavonols [7]. Anthocyanin composition in red raspberries (R. idaeus) is more diverse and the most abundant pigments are cyanidin 3-sophoroside, cyanidin 3-glucosylrutinoside, cyanidin 3-glucoside and cyanidin 3-rutinoside, depending on the cultivar [9,[11][12][13]. Black raspberries (R. occidentalis) are rich especially in cyanidin 3-sambubioside, cyanidin 3-rutinoside, and cyanidin 3-xylosylrutinoside [14].…”

Antioxidant properties of fruits of raspberry and blackberry grown in central Europe

Fruits of several, mainly Polish cultivars of floricane-and primocane-fruiting red raspberry (Rubus idaeus), black raspberry (Rubus occidentalis) and blackberry (Rubus fruticosus), grown in central Europe during two successive vegetation periods, were investigated. The content of phenolic compounds, including anthocyanins, as well as antioxidant properties of fruit extracts were analysed. A number of methods were employed: ferric ion reducing antioxidant power (FRAP), cupric ion reducing antioxidant capacity (CUPRAC), 2,2-diphenyl-1-picrylhydrazyl (DPPH) radical scavenging capacity involving both colorimetric and EPR spectrometric measurements. From among all the tested fruits black raspberries had the largest antioxidant capacity as verified by all methods used in this study. These berries were also the most abundant in phenolic and anthocyanin compounds. Blackberries were characterised by larger antioxidant capacity than red raspberry fruits which were accompanied by higher content of total phenolics and anthocyanins. Berries of primocane-fruiting cultivars, often used for intensive agricultural production, generally did not differ in the total phenolic and anthocyanin content as well as in the antioxidant capacity as compared to the traditional, floricane-fruiting ones. The research contributes to deep characterisation of central European berry fruits which due to their high content and large diversity of health-beneficial compounds are classified as natural functional food.

“…As reported by ACOSTA-MONTOYA et al (2010), the main phenolic compounds determined of blackberries were ellagitannins (lambertianin C and sanguiin H-6) and anthocyanins (cyanindin-3-glucoside and cyanidin-3-(6'-malonyl) glucoside), and in the semi-ripe fruit ellagitannins accounted for more than 92% of phenolic compounds and 61 % in ripe fruit. Ellagitannins, also referred to as hydrolysable tannins or ellagic acid derivatives (LEE et al, 2012) which are identified as active principles in traditional Chinese medicines (QUIDEAU, 2009) and are major phenolic compounds. These compounds are certainly associated with the antioxidant activity (SIRIWOHARN et al, 2004;ACOSTA-MONTOYA et al, 2010).…”

RESUMO Algumas frutas de clima temperado e tropical, principalmente as do tipo "berries", têm como característica o acúmulo de compostos antioxidantes e são objeto de inúmeros estudos, haja vista a sua correlação com os benefícios para a saúde humana. Os objetivos deste trabalho foram quantificar as antocianinas, os compostos fenólicos e mensurar a capacidade antioxidante (ferric reducing antioxidant power -FRAP) de amoraspretas de duas cultivares ('Brazos' e 'Tupy'), nos três estágios de maturação, considerados verde, semi-maduro e maduro, e dos seus produtos (polpas e fermentados). No processo de maturação da

“…Previous studies show that the plants of genus Rubus contain the compounds with antioxidant and anti-inflammatory properties including a variety of antioxidants (such as Neoxanthin, Violaxanthin, β-carotene, Lutein) and anthocyanins (such as Cyanidin-3-glucoside, cyanidin-3-xyloside, cyanidin-3-rutinoside, cyanidin-3-malonylglucoside and dioxalylglucoside-cyanidin-3), vitamin C, flavonoid and phenolic compounds (such as ellagic acid, catechin, epicatechin, rutin, quercetin, caffeic acid, p-coumaric acid) and minerals (such as calcium, iron, magnesium, phosphorus, potassium, sodium, zinc, manganese and selenium) (17,(33)(34)(35). So by abovementioned description, it can be assumed that compounds in hydroethanolic extract of aerial parts of Rubus fruticosus suppress inflammation caused by diabetes by affecting on inflammatory mechanisms and exerting anti-inflammatory effects and inhibiting enzymes involved in this pathway such as lipoxygenase and cyclooxygenase.…”

Background: Diabetes mellitus is the most common metabolic disorder with many complications such as neuropathic pain which relief from it is a dilemma. Objectives: To investigate the effect of hydroethanolic extract of Rubus fruticosus on neuropathic pain in diabetic rats. Materials and Methods:In this experimental case -control study, forty eight male Wistar rats (250±20 g) were divided randomly to non-diabetic and diabetic groups. Streptozotocin (60 mg/kg, intra-peritoneal) was used to induce experimental diabetes. Each group was divided into three groups: receiving orally normal saline, 100 and 200 mg/kg doses of Rubus fruticosus extract for 30 days. At the end; the rats were subjected to Tail-Flick test. The data were analyzed by one-way and two-way ANOVA followed by Tukey's test in SPSS 21. Results: In a paired comparison, all diabetic groups had shorter latency of tailflicking time (p < 0.01) and lower pain tolerance threshold. Also among diabetic rats, significant differences existed between saline group and group receiving the extract at a dose of 100 mg/Kg (p < 0.01), between saline group and the group receiving the extract at a dose of 200 mg/Kg (p < 0.001) and also between the groups receiving extract at two different doses (p < 0.001). But, only diabetic group receiving the extract at a dose of 200 mg/Kg showed positive significant difference with non-diabetic control group (p < 0.01). Conclusions:The hydroethanolic extract of Rubus fruticosus can heighten the pain tolerance threshold and reduce the neuropathic pain induced by diabetes mellitus.
